<p>In the cutting apparatus for cutting a porous concrete block which is still in a plastic condition, the cutting table comprises a plurality of bars (5) which are disposed parallel and at a spacing from each other. The bars (5) are mounted horizontally displaceably perpendicularly to their longitudinal direction while provided between the bars (5) are spacer members (20) which restrict the movement of the bars relative to each other when they are pulled apart and pushed together, to the width of the cutting gap, such that the mutual spacing (S) of the bars (5) which are drawn apart prior to the cutting operation can be reduced by the width of the cutting gap after the cutting operation, by pushing the bars towards each other. Each bar (5) is divided in its longitudinal direction along a vertical plane (V) and comprises two bar halves (5a, 5b) which are adjustable horizontally relative to each other perpendicularly to the longitudinal direction and the mutual spacing (a1) of which is adjustable by means of a respective adjusting device (8) engaging each of the oppositely disposed ends of the bar halves (5a, 5b). Also provided at each adjusting device (8) is a coupling means which permits the two bar halves (5a, 5b) which together make up a respective bar (5) to be completely released.</p> |
